Olawale/FreeCodeCamp Algorithm: Title Case a Sentence

titlecase_a_sentence.js

function titleCase(str) {
    return str.split(" ").map(function(each){
      return each.replace(each.charAt(0),each.charAt(0).toUpperCase()).replace(each.substr(1,each.length), each.substr(1,each.length).toLowerCase());
  }).join(" ");
}
titleCase("I'm a littLe tea pot");

/**
My Old solution below 

function titleCase(str) {
  // Convert the whole string into lowercase then split it into an array with each word as an element
  var strArray = str.toLowerCase().split(" ");
  // Create an empty array to keep each word when successfuly converted
        var newSentence = [];
   // Do a for loop on the array containing each word
        for(i=0;i<strArray.length;i++){
      // Convert the first character of the item at the present iteration into uppercase with str.replace()
      //When done, push the word into the newSentence array
      newSentence.push(strArray[i].replace(strArray[i].charAt(0),                      strArray[i].charAt(0).toUpperCase()));
        }
        // Join the new sentence array into a string and return it
        return newSentence.join(" ");
        }
